I've had much better experience with Apples to Apples. It depends a lot on the group.
Truth. It does depend on the group and what their level of humor is at. I find myself passing on playing CAH and A2A because I didn't want to deal with the group. If it's a witty group, then I'm on board.
I like the structure of CAH where you are filling in blanks for sentences. With A2A, it's mostly word association. That can be funny (I was rather pleased with playing Joan of Arc for Sultry, though the judge didn't get it *shrug*). I like to try to be clever in my card choice. For that reason, I actually cheer at Pick 2 or Pick 3 in CAH. It allows me to get rid of those boring cards when they're paired up with other boring cards.
And the boring cards are what make CAH worse. Some cards are simply more excitable than others. Hell, you can read off some of the cards without any context and be guaranteed a snort from someone. A2A doesn't really have that. All cards are homogenously boring. So for that reason, A2A requires greater thought when hooking up a noun with an adjective. Meanwhile, in CAH, if the judge is the type to start busting out laughing at unicorn-humping, then your carefully chosen card probably won't get picked because unicorn-humping.
I like CAH, but I only like it with the right group. Otherwise, I tolerate it. It's fun, but I'm all for ending the game early.
